Isdn 60 Retard

Isosorbide dinitrate, the active ingredient in Isdn 60 Retard, is an organic nitrate presented as a sustained‑release oral tablet for oral use. It is employed to relieve angina pectoris and to improve symptoms in chronic heart failure patients who require long‑acting anti‑anginal therapy. The formulation provides a controlled release of the nitrate over several hours, helping to maintain stable plasma concentrations and reduce the frequency of dosing.

GNH USA supplies Isdn 60 Retard as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, pharmacies and clinics worldwide.

Isosorbide dinitrate is an organic nitrate used to manage coronary artery disease and heart failure. - Angina pectoris: reduces frequency and severity of chest pain by decreasing myocardial oxygen demand. - Chronic heart failure: improves exercise tolerance and symptoms by lowering preload and afterload. - Stress‑test induced angina: prevents ischemic episodes during diagnostic exercise testing.

Isosorbide dinitrate may cause a range of adverse reactions, varying from mild to serious.

Common Side Effects: - Headache - Dizziness or light‑headedness - Flushing - Low blood pressure (hypotension) - Nausea

Serious or Rare Side Effects: - Severe hypotension leading to syncope - Myocardial infarction in susceptible patients - Allergic reactions such as rash or anaphylaxis - Methemoglobinemia (rare) - Vision disturbances

When prescribing Isosorbide dinitrate, clinicians should observe several precautionary measures to ensure safe use. - Dose titration: start with the lowest effective dose and increase gradually under medical supervision. - Concomitant PDE‑5 inhibitors: avoid use with sildenafil, tadalafil or similar agents due to risk of profound hypotension. - Blood pressure monitoring: check blood pressure regularly, especially after dose adjustments. - Tolerance development: assess for reduced efficacy over time and consider drug‑free intervals if needed. - Hepatic or renal impairment: use with caution and adjust dosing as appropriate. - Store at room temperature: keep in the original container, protect from moisture and heat.

Isosorbide dinitrate can interact with several medicines, altering its effect or increasing adverse reactions.

Major Interactions (Avoid): - Sildenafil, tadalafil, vardenafil (PDE‑5 inhibitors): may cause severe hypotension. - Other nitrates (nitroglycerin, isosorbide mononitrate): additive vasodilatory effect leading to dangerous blood pressure drop. - Sodium nitroprusside: excessive vasodilation and hypotension.

Moderate Interactions (Monitor Closely): - Antihypertensives (ACE inhibitors, beta‑blockers, calcium channel blockers): may enhance blood‑pressure‑lowering effect. - Diuretics: can increase volume depletion and orthostatic hypotension. - Alcohol: may potentiate hypotensive response.
